Tia Hatton, a University of Oregon student majoring in environmental studies, published this essay in Sierra Magazine about why she became a plaintiff in the case Juliana, et al. v. United States of America. Hatton and 21 other young climate activists are suing the U.S. government in a landmark case for failing to take meaningful action on climate change. The trial begins in early February 2018. Lawyers hope to prove that the US government knew for decades about CO2 pollution and rising global temperatures. Photo credit: Tia Hatton
